In the practice -;o f the; present invention,

40 the'book cover is, of course, removed. The

fold ofheach signature is then'cut oif sufficiently to remove all paper. touched by' the old'sglne and produce silbstantial evenness in the frail worn portion ofthe leaves. {With the book lying on its side, each leaf, as 1, is removed :and its binding edge is skived,

'It will be understood, however, "that,,i prior to binding, the leaves are arranged so that their free: edges will be even and the oints,

consequently, will not always assume the exact regular relation shown. iilkfterthelfme e'clges ofthe leavesfhave been made 'even, theed'ges of the'bin-der strips are-trimmed- V evenly arfd"'the "repaired sheets mayi'be per- 7 n Under some conditions the? leaves mayj be alsojs'kived, in groups, 7', thereby expediting the work as :a plurality of leaves or strips may be passed through the skivingimachine The joints 5 8 will extend Of theibook with a corresponding increase 7 A in thestrength";and" flexibility 0f the leaves.

It is to n be *nnder stood that I the binder" -strips are' ot new paper preferably a. little thinner than'the old paper in the' leaves so as to permit aneasy roll without forcing the bend into the old 'paper,}and the ,skiving eliminates swells fromthe rep air d h s the binding being applied to the'new binder ,stripsso" that the old paperi is relieved of; all 5 folidin-g strain. fThe joint obtained by the described method ris very "strong, the "old and the new paper being practicallywelded into a singlecontinnous'sheet. The teXton the pages is not obscured, as no paster strips which are apt to extend ,overontojthe text are-employed "Thereisxno-definite break- W ing point "in the repaired sheet whereas re 7 bound books which have cambric or other material at the binding contain a definite breaking point which is found along the edge of such material.

Should a free edge of a leaf be badly worn, it may be repaired according to my described method, and in Figure 5 I have shown a leaf 9 all the edges have been so repaired. The binding repair strip 3 is the same as that previously described. All the edges of the leaf are skived and facing repair strips 10, 11, and 12 are provided and each skived along a side edge to mate with one skived edge of the leaf. Some of the strips are also skived at their ends or at an end to form a lap joint with ameeting strip, as indicated at 13 and 14, and the location of these end skives may be determined in any convenient manner as by measurement or a preliminary test setting. Theskived edges are then coated with adhesive, fitted together, and dried under pressure as before described. The free edge strips will preferably be narrower than the binder strips but will have the same thickness as the old paper.

It may, sometimes,,be found necessary or desirable to repair all the leaves of the book in which event the form of the invention illustrated in Fig. 6 may be employed. In this arrangement, the leaf is skived on all four edges, as in Fig. 5, and a signature consisting of four sheets of new paper of the same thickness as the old paper is provided. Each sheet, as 15, is divided into two leaves by a medial fold, as indicated at 16, and in each leaf is cut a window 17, all four edges of the window being skived as indicated at 18. Each windowed repair sheet is numbered as at 19, according to the old sheet it is to receive, adhesive applied to the edges of the windows and of the old sheets, the old sheets fitted to the windows, and the whole placed in the drying press as in the previously described methods. When thoroughly dried, the repaired sheets may be bound in any desired manner, by sewing through the fold or by whipstitching or by loose-leafbinding, and if they are to be made. up loose-leaf or whipstitched, the sheets will be cut through at the folding point and a little more width allowed on the binding edge. The sheets will, of course, be assembled with due regard to paging in the usual manner, the first sheet, for instance, carrying pages 1,2, 15 and 16, the next upper sheet 3, 4, 13 and 14, the third sheet 5, 6, 11 and 12, and the top or innermost sheet of the signature 7, 8, 9 and 10. One leaf is shown fitted in the window provided therefor at 20.

In the form of the invention shown in Figs. 7, 8 and 9, two leaves 21, .22, of a signature, say, pages 2 and 15, have their binding edges skived, as at 23, in the manner previously described,. the skives being relatively reversed. A binding strip 24 is provided having the same length as the leaves 21 and 22 and its side edges are skived to mate with the skived edges of the leaves, as clearly shown in Fig. 7. This binding strip is then disposed between the leaves, as shown in Figs. 7 and 8, and secured thereto by 1. A method of repairing books which includes separating the leaves from the old binding, uniting a binder strip to each leaf at an edge thereof, the joiningedges of the leaf and the strip being skived whereby to form a joint passingthrough and diagonally between the opposite surfaces of the leaf,

the edge-of the binder strip parallel with the joint being free to be secured in the book cover. a

2; A method of repairing books which includes separating the leaves from the old bindings, skiving the'leaves along the binding edges thereof, skiving one side edge of each of a plurality of binder strips, imposing a binder strip upon each leaf with the skived edges in contact and coated with ad hesive, drying the adhesive under pressure, and binding the strips.

3. Abo'ok leaf having a repair strip attached to its edge, the meeting edges of the strip and the leaf overlapping and forming a joint passing through and obliquely 'between the opposite surfaces of the leaf.

4. A book leaf consisting of an old leaf having its edges skived, and a repair member having edges skived to lap the edges of the leaf and adhering thereto and having an unskived edge to be secured in a book cover.

5. A method of repairing books which consists in separating the leaves from the old binding, skiving the edges of the leaves, providing a frame for each leaf, skiving the inner edges of the frame to matewith the skived edges of the leaf, applying adhesive to the skived edges, imposing skived edges of the frame on skived edges of theleaf drying the adhesive under pressure, and securing an unskived edge of the frame in the book cover.

6. The method of repairing books which consists in separating the leaves from the old binding, skiving the binding edges of the leaves, laying two leaves side by side in spaced relation with skived edges opposed,

inserting a binder strip having skived edges between the skived edges of the two leaves with the skived edges of the strip imposed on the skived edges ofthe leaves, and uniting the binder strip to the leaves.

In testimony whereof, I have signed this specification.
